THE SHORT ANSWER

Is HFS87 worth a closer look?

HFS87 shares the widest cut here, 87 inches, with Blue Diamond’s 403740, but its 30–85 hp range reaches far smaller tractors, and it lists Category I and II. Its gearbox is rated only 50 hp, and its 1,299 lb with the shaft is close to the 24-inch lift of many compact tractors; check both before buying.

The seller confirms the exact setup, current price and delivery. No field test or manufacturer-confirmed pairing is claimed.

THE BUYING PERSPECTIVE

Know before you order.

  • Product page and manual give a 30–85 HP tractor power range without identifying PTO versus engine horsepower; the product URL says 35–85.
  • Both list the gearbox at 50 hp (36.75 kW), well below the 85-hp top of the tractor range. Farmry treats the gearbox as a separate component rating; ask Farmry what tractor power the gearbox is meant to see.
  • The manual gives a 2,200-mm (86.6-in.) cut and 2,425-mm (95.5-in.) overall width; the page rounds to 87 and 96 inches.
  • Ask Farmry whether its 30–85 HP requirement refers to engine output or PTO output.
  • Check three-point geometry, actual lift capacity at the implement load center, front ballast and axle limits.
  • Check PTO shaft length, overlap, shielding and clearance across permitted hitch travel; quick hitches change geometry.
